-This invention relates 'touid 'dispensing devices, and more particularly:.to` stripinginstruments. "l

One of the objects ...A ..I of theinvention is toprovide a uid dispensing instrument that canvbe: l moved along apiece of Workrby an unskilled operato-r to apply a -relatively wider-stripe of uniform width and thickness.` 2 l.

Another object of the invention is to provide a plural nozzle striping instrument that will apply. marginal stripes in advance of 'a ller stripe as it is moved along a work piece. s

Another object ofy the inventionis to provide a plural nozzle stripinginstrument'in which a strand of wire is utilizedto 4holda-the nozzles in endwise position on their=fulcrums and to also hold down'the dispensing end of one of the4 nozzles. .v

Anotherobject of the a plural nozzle striping-T instrument in Which'a member is utilized toflimit the depressionof.

fulcrumed nozzles and to :also serve as an anchor for spring means exerting pressure to depress the dispensing ends ofthe nozzles. y

Referring'to the drawings byfcharacters of reference, I9 is the mainmember of the striping in-4 strument body structure on which the uid reser-` voir, pump mechanisms Y'and' dispensing nozzles arecarried. Shaft Il' projects from one side of the body member and fixed thereon is a roller i 2- thatv serves to drive the shaftvand -to guide the instrument. The-side ofjthe bodymember, fopposite that from whichftheshaft-projects, is formed with a recess =I3` for-'accommodating a series of plates I4, I5, I6 and I'Is'ecured =byfscrews I8, and these plates and-the body-member form the-body structure. Plate' I5 is formed With a recess that vcont'ainsmeshing pump gears I9- and .invention is to. provide lik a corporation oir? Michigan I ,Y y f Application Marcil 1`1, 1942, seriaLNo. 434,167 y. (gli {HJ-62.5) y u u y M I. u provided in the plates ior feedingpaint, or some similar fluid, from sleeve 24 to the recesses containing the pump gearings. The Yfluidis `dispensed from the instrument through a plurality ofy nozzles 26, `21 and 28 having trailing 'outlet portions yarrangedtovapply a single relatively wide stripe to a flanged Work piece 29. Nozzle 26 has a hub portion 30 fixed to sleeve'3l and nozzle 28 has a hub portion 32 xedto cap sleeve 33. These sleevesare journalled end to endon'a stal 69 fixed to and projecting from the instrument body member I in parallel-relation .with shaft il. Sleeve 33 spaces the nozzle 23 from the nozzle 28 sufficiently so that nozzle `2'! can lie therebeftween. Stai 69 is formed witha-'pair of bores 36 and 35for. feeding fluid to the nozzles journalled thereon, such passages communicating with passages 36 and 3l in thebody.. Gears 2land22 force fluid into passage -36 While gears22 Q0 and 23 force iluid into passage 3l.

- Nozzle 21 has a hub portion 38 xed to a sleeve 39 which journals on sleeve staff 4l) iixed to and projecting fromplate .I6 in parallel relation with` stal 60 but in a lower plane'andiorwardly thereof. The interior of staff d communicates with a circling the outer end of sleevex33 and engaged against hub 32. The wire extends parallel with the nozzle sleeves 3| and 33 and is bent to anchor around screwi i4 fixed to the instrument body. The wire is :bent at 45 andnthen coiled at QB to encircle sleeve 39, and thev end of the Wire is bent over the nozzle hub 38 andxed Ito the outer end of nozzle sleeve 39.. This `arrangement of the wire retains nozzle .sleeve 39 from axial displacement on the staland exerts torque on the sleeve normally suflicient'to hold the dispensing end of nozzle 2l in contact.l with the work piece.

The' nozzlesare restricted in their downward movement bylalmember 5U 'that is xed to and projects from the side of the body member I in parallel relation with .the stafisfand the shaft. This memberrcan be in the form of a rod that also serves as an anchor for coilspringsl and l 52. Springl isf connected to pin 53 on nozzle hub v32 and spring 52 isconnected by pin 53 on nozzle hubv 3i).v 'Handles 55, 56 and 57 are fixed to the-no'zzlesfand extend rearwardly to overlie the memberv 50. AThe handles are so arranged that the nozzle outlet ends are in substantially thesamehorizontalplane when the springs engage them with member 50. Pins 58 extend through the dispensing portions of the nozzles and are located behind the outlet open-` ings. Such pins bear against the Work Piece and hold the nozzle outlets clear to dispense fluid.

The work piece 29 is formed with a pair of parallel upstandingibeads 10 and'l'f and. the instrumentis designed to 'apply' ay stripe on the intermediate surface l2. arranged to roll on the work piece surface outside of bead 10,'which serves as a guide therefor, and the nozzles will lie between the beads. The instrument is moved al"ong"the` workpiece in such relation and the guide wheel' will rotate the pump shaft and thereby cause striping duid to be moved through the nozzlesl ontdthe' work. piece surface in a uniform amount regardless of the speed of instrument movement.

A Asshown in Figs. 1 and 3, the nozzles 28 and 28` are. parallel andA their dispensing. ends lead.

the. outlet'. end of the intermediate` nozzle' 2.1 when applied to and moved over: a. work piece surface.. The nozzles 26 and. 28.` will thus rst;

apply marginal stripes on `the surface over whichV the instrument. is ymoved and.' theV intermediateV trailingnozzle will fill in the space on the sur.- face between the marginalstripes. By. this mannei` ofv paint. application, the marginal stripes. will have an opportunity to dry to some extent beforethespace therebetweenis lled in and thusthe possibility of the striping uid running. beyond. the desired margins. of. a. relatively wide' stripe isireduced...

The stafll) and spring anchor. member 50 areV Vin, substantially the same horizontal; plane.- so

that. the least downward pressure is exerted against ther nozzles when their.. handles rest. against member. 50., The pressure is relatively light when these nozzles contactl the. workpiece and. hencethe work surface. will be marred a. minimum extent by thefrictionalcontact.of the nozzles withv the work piece surface whenl applyinga stripe.

Although the invention has been described in connectionwith a specific embodiment, the principles involved .are susceptible of4 numerous other applications'. which will readily occur to persons. skilledin the art.
